Refers to one of two
despicable actions regarding illicit affairs:
(1) taking steps to make said dallying --- or an unexpected "result"; i.e.
one or more offspring --- seem proper and correct, or
(2) indulging in a little nooky-wooky with
one or more fellow customers in a room full of coin-operated Maytags, Whirlpools, and Speed Queens.
If you
accidentally conceive
a child by "doing it" while "doing" your wash, you may need to enlist someone with savvy
diplomacy to perform a little philaundering for you, and thus avoid a public scandal.
